My invention relates, more particularly, to bottle-capping machines comprising an u pright having a base and carrying a cappinghead, and means on the head engaging the upright and by whichthe desired cap-applying pressure is exerted against a cap applie to a bottle positioned on the base. v

My primary object is, generally stated, to provide a novel, simple and inexpensive' arrangement of parts operative to e'tfec't the automatic lifting of the capping head to normal position after release by the opera-tor of the means for forcing the capping-head to cap-securing position. y .Referring to the accompanying drawing:- e l l Figure 1 is a side Vview of the machine. Figure 2 is a plan sectional View taken at the line 2 on Fig. 3 and viewed in 'the direc-tion of the arrow. Figure 3 is a detailed view of the capping head of the machine, 'this v iew being taken at the line 3--3 on Fig. 2y and viewed in the ldirection of the arrows. Figure4 is a section taken at the line 4 on Fig. 3 .and viewed in the direction of the arrow; 'and Figure 5, a view 'in edge elevation 'taken at the line 5 on Fig. 3 and viewed in the direction of the arrow. A

The construction of capping mechanism illustrated comprises generally a basef6,an upright 7 secured to and rising from the base 6 adjacent an edge thereof, a capping head 8 slidable up and down on the upright 7 and means for actuating the head 8.v i The upright 7 is Vshown as for-med of two bars 9 having straight upper portions v10 jat which they fit flatwise together 'and are riveted in position as represented at 11. The lower 'ends of the bars 9 are deflected downwardly 40 and outwardly relative to each other, and

therefore convergent. n The body of the capping head 8 is preferably for-med of a single 4sheet of metalbent int'o general U-shape topresen't substantially y parallel spaced apart plate portions 12 at which the head straddles the upper portion of the upright 10, these plate portions being riveted together at 13. The cap-engaging die-portion of the head 8, which may be of any desirable form such, for example, as commonly provided in machines for this purpose, is represented at 14 and is rigidly connected to the plate portions 12 by outwardly bent lugs 12*i on the bottom edge portions of these plate-portions. l

The ,means for actuating the capping .head

8 comprise a rack 15 on the upper bar-.portion of the upright 10,1this rack, in the particular l construction shown, being formed vbyy cutting teeth'in the adjacent edges of the straight portions 'of the bars forming the upright(V The rack is provided for cooperation withthe segmental gear portiony 16 of a lever 17 which is located between the plate'y portions 12 and is fulcrumed. on a pin 18 carried by these plate portions and so positioned as to cause the lever to mesh at its gear-portion with therack 15. y

flhe lever is so formed as shown that whenit 1s swung to uppermost position," generally parallel with the upright, the gear portion 16 is disengaged from the rack 15 and the capy ping head with the parts carried thereby may befreely adjusted along the rackto any desired position of. initial engagement of the gear with the rack for bottles ofdierent heights, or, if desired, maybe lifted free of the u right to disengage the Ahead from the l uprig t, this being especially desirable where it is desired to reverse the position of thehead on the upright, in which position the lever depends, as for example yto economize in the space .occupiedv by the machine which is l'an important factor especially in shipping.

The arrangement of the parts is such that in the initial engagement of thegear'with the rack the lever17 extends in anupward direction and the capping pressure applied to a vcap on a .bottle positioned on the base V6, is

exerted by swingingthe lever outwardly and downwardly, the head 8, in. this operation descending.

rTo provi K y the head Sand lever 17 in raised position'with the die-portion 14 clear of the bottle andthe return of vthese parts to such position,v after the capping operation, I provide a'eoi'l spring 19 which is located between the platesportions 12 at the open side of the head, one end of this spring being releasably connected with the head by a split pin 2O extending through the plate portions 12 and through an' eye 21 on the spring and its other end being connected, by an eye 22 thereon, with the lever 17 as shown, these parts being so arranged that in the rocking of the lever 17 to depress the capping head the spring 19 is placed under sufde Vior vthe normal positioning of icient tension to throw the lever 17 upward and raise the head 8 and lever when the operator discontinues downward pressure thereon.

The spring 19 is somewhat wider than the the edges of the plate portions 12 as represented at 24.

It will be understood from the Jforegoing description that a machine embodying my improvements is not only of simple and inexpensive construction but is rugged and highly resistant to the stresses imposed on it in use. Furthermore, the machine comprises the minimum number of parts and adapts itself to replacements, in case of impairment of parts with quick facility, it being noted that the spring 19 by being located as shown and described, does not require for its attachment the use of a separate plate or bracket on the head and by being secured in place in accordance with the showing may be readily removed and substitution of another therefor quickly and easily effected.

While I have illustrated and described a particular embodiment of my invention, I do not wish to be understood as intending to limit it thereto as the same may be variously modified and altered without departing from the spirit of my invention.

What I claim as new, and desire to secure by Letters Patent, is

1. A capping machine comprising an upright, a capping head slidable along said upright and presenting spaced-apart plate portions, means located between said plate portions for lowering said head on said upright and a spring located between said plate portions and extending to one side of .said upright and engaging said means and head for returning said head to raised position.

2. A capping machine comprising an upright, a capping head slidable along said upright and presenting spaced-apart plate portions, means located between said plate portions for lowering said head on said upright and a spring located between said plate por tions and extending. to one side of said upright and engaging said means and head for returning said head to raised position, said plate portions having outwardly deiiected portions to accommodate said spring.

3. A capping machine comprising an upright, a capping head slidable alongv said upright and presenting spaced-apart plate portions, lever means located between said plate portions for lowering said head on said upright and a spring located between said plate portions and arranged to co-act with said lever and saidv plate-portions for returning said means to raised position.

l. A capping machine comprising an upright, a capping head slidable along said upright and presenting spaced-apart plate portions, means located between said plate portions for lowering said head on said upright and a spring located between said plate portions and connected at its opposite ends to said plate portionsI and to said means for returning said head to raised position.
